The earthquake was reportedly felt in the Soviet Union. Tectonic setting Myanmar lies at region where the Indian, Burma and Eurasian plates collide; with the Burma plate wedged between. The north-northeast motion of the Indian plate towards the Eurasian plate has resulted in the formation of two major plate boundaries along the Burma plate; the Sagaing Fault to the east, and a complex convergent boundary accommodating oblique subduction of the Indian plate beneath Myanmar. Subduction of the Indian plate occur along the Arakan Megathrust; the northern continuation of the Sunda Megathrust; capable of generating an earthquake greater than magnitude 8.0. The w 8.5–8.8 Arakan earthquake of 1762 is believed to be a thrusting earthquake on the Arakan Megathrust.Mondal Dhiman R. McHugh Cecilia M. Mortlock Richard A. Steckler Michael S.

These earthquakes have hypocenter depths that range from 60 km to greater than 200 km. Earthquakes including the w 7.0 1975 Bagan earthquake, as well as the April and August earthquakes of 2016 were associated with intermediate-depth intraslab activity.International Seismological Centre Online Event Bibliography http://www.isc.ac.uk/cgi-bin/FormatBibprint.pl?evid=725977 International Seismological Centre 6 August 2021 Earthquake The earthquake had an epicenter location in a remote and sparsely populated area, more than 200 mi from Mandalay, Myanmar and Shillong, India. Many small settlements however, including Homalin, Maungkan, Hta Man Thi and Kawya were in close proximity to the location of the quake.7.3 Earthquake Rocks India-Burma Border Los Angeles Times https://www.latimes.com/archives/la-xpm-1988-08-06-mn-6911-story.html West of where the earthquake nucleated, lies the Chin Hills-Arakan Range, a mountain belt formed by the collision of the Indian and Burma plate, similar to the continental collision seen in the Himalayas. The focal mechanism of this event indicated oblique-reverse faulting at an intermediate depth of 90 km within the Indian plate.Focal Mechanism https://earthquake.usgs.gov/earthquakes/eventpage/usp0003jpw/focal-mechanism United States Geological Survey Impact Two people were killed, 30 were injured and another 30 were missing in Bangladesh after seiches formed in the Jamuna River at Dhaka, causing a ferry boat to capsize.Tsunami Event Information National Geophysical Data Center / World Data Service (NGDC/WDS) National Geophysical Data Center, NOAA 10.7289/V5TD9V7K 1972 Data Set https://www.ngdc.noaa.gov/hazel/view/hazards/tsunami/event-more-info/2372 live https://web.archive.org/web/20210709190453/https://www.ngdc.noaa.gov/hazel/view/hazards/tsunami/event-more-info/2372 2021-07-09 An additional two lost their lives in Northern India. Large-scale landslides, fissures and liquefaction events were reported in India and Bangladesh. Subsidence of 20 cm was recorded in Gauhati, India. It was felt throughout Bangladesh and northeastern India, including Calcutta. The earthquake was also felt in parts of northwestern Myanmar and Kathmandu, Nepal. Shaking from the earthquake caused significant damage to human infrastructures, railroads, and roadways. Shaking from the earthquake was felt throughout northeast India with a Modified Mercalli intensity of VII (Very strong).Kumar Brijesh Isoseismals of Burma-India border region earthquake of August 6, 1988 Bulletin of Indian Society of Earthquake Technology 29 1 57–67 https://iset.org.in/public/publications/80098.pdf In Assam, India, severe liquefaction severely damaged roads and bridges in the National Highway 37 system. Hotel Regale in Silchar suffered extensive damage due to liquefaction; subsiding floors and cracked walls. Many aged or traditional structures not made to withstand an earthquake were damaged beyond repair. A section of an embankment slumped away, leaving a railroad between Borlongphar and Langchiliet hanging 8 meters above the ground.M. K.
